Why can't we use diamond tools to process iron materials?
When the temperature is over 800 DEG C, the diamond will lose its cutting ability, and it has strong chemical affinity with the iron. At high temperature, the carbon in the diamond will soon spread to the iron, so that the edge of the crack". Therefore, diamond tools are not suitable for the processing of ferrous metals. Because of its high brittleness and poor impact resistance, it is very sensitive to vibration
If you have to use diamond tools to process the iron material, you need to do a good job cooling, increasing the chip space, reducing the cutting force and other points, it is possible to process iron materials
General black metal mainly including iron and steel, both carbon and these materials exist, can be said that the black metal is pro carbon material, diamond composition is carbon, with diamond tool in machining iron-based materials, diamond surface carbon and easy cutting, cutting surface adhesion occurs, leading to the tool is not sharp, by processing the temperature rise, the temperature is high, and oxygen in the air to exist, the diamond is prone to macro elements carbonization and graphitization of diamond. This is why diamond tools are generally not processing of ferrous metal materials.
